Data corruption is the damage of information caused by various hardware or software problems. When a file is damaged, it will no longer work correctly, so an app will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an administrator, which makes it a significant problem for web hosting servers as fails are more likely to occur on larger hard disk drives where vast volumes of info are located. If a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a standard one and will be copied on all drives, making the harm permanent. A huge number of the file systems that operate on web servers nowadays often are unable to find corrupted files right away or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Website Hosting

The integrity of the data that you upload to your new website hosting account will be guaranteed by the ZFS file system that we employ on our cloud platform. The vast majority of web hosting service providers, including our firm, use multiple hard disks to keep content and because the drives work in a RAID, the same data is synchronized between the drives at all times. When a file on a drive becomes damaged for some reason, yet, it is more than likely that it will be copied on the other drives since other file systems do not have special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for every file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy will be swapped with a good one from another hard disk. Because this happens instantly, there is no possibility for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any probability of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created employ a powerful file system known as ZFS. Its advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. Since we save all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. If there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens instantly, there's no chance that a damaged copy could remain on our hosting servers or that it can be copied to the other hard drives in the RAID. None of the other file systems use such checks and furthermore, even during a file system check after a sudden power failure, none of them will identify silently corrupted files. In contrast, ZFS will not crash after a power loss and the continual checksum monitoring makes a lenghty file system check unnecessary.
